HABRY B. HULL, OF DAYTON, OHIO, ASSIGNOB, BY MESNE ASSIGNMENTS, TO FBIGII AIRE CORPORATION, A CORPORATION OF DELAWARE BEFRIGERATING APPARATUS Original application filed January 21, 1925, Serial No. 3,789. Divided and this 11, 1925. Serial No. 74,727. v

The present invention relates to the construction of refrigerator cabinets and is a division of my copending application Serial No. 3,789, filed January 21,1925.

One of the objects of the present invention is to reduce the cost and facilitate the manufacture of cabinets by constructing and arranging the parts of a cabinet in such a manner that the variations of dimensions of the inner parts of the cabinet will not afi'ect the assembling of the outer walls of the cabinet.

Further objects and advantages of the present invention will be apparent from the following description reference being had to the accompanying drawings wherein a preferred form of embodiment of the inventionis clearly shown.

In the drawings:

Fig. 1 is a fragmentary section view of the upper portion of the improved cabinet, the section being taken on line 1-1 of Fig. 2, and showing a mechanical refrigerator machine in elevation applied thereto.

Fi 2 is a sectional view taken on line 22 of Fig. 1, showing the cover for one of the compartments removed and showing the machine in lan.

Fig. 3 1s a front view in elevation.

Fi 4 is a sectional view taken on line 4--4 of Fig. 3, showing the machine removed.

Fig. 5 is a sectional view taken on line 5-5 of Fig. 3, and I Fig. 6 is an enlarged fragmentary vlew'm elevation of alower portion of the cabinet.

Referring to the drawings, the refrigerator cabinet 20 is provided with side walls 21 and 22, a back wall 23, a top wall 24 and a front wall 26-. Front wall 26 includes an opening closed by a door 28 providing accessto the interior of the food compartment 32 of the cabinet.

The cabinet is divided into three compartments including a cooling compartment 30, a machine compartment 31 and the food compartment 32, which is located under compartments 30 and 31. The food compartment 32 is provided with a box like lining 33, having enclosing side walls 33a, 33b, 33c

and 33d, and a back wall 33e. The sides 33b and 330 carry studs 34 which support shelves walls 37, 37a, 38 and 3811 which extend above vertical walls37, 37a, 38 and 38a to provide present 7 application filed December 35. Corkboard insulation is secured to the sides, back and bottom of the lining 33. Cooling compartment 30 is provided with a lining 36 surrounded by non-conducting vertical the lining Near the upper edge, the lining 36 ,carrles brackets 39 which support a removable top 40 of insulating material havmg an inside lining 41. The wall 40 is slightly smaller than the opening provided by the,

a space between the said vertical walls whereby an insulating material 42, such as rubber, can be jammed between the edges of the wall 40 and the surrounding vertical walls. After the insulating material 42 has been removed the top 40 can be readily re-' movedto provide access to theinterior of compartment 30. A bottom wall 47 of lining 36 slopes downwardly toward one side of the cabinet and provides a gutter 44 as shown in Fig. 4. ThlS bottom wall 47 is separated from the top wall 33a of food compartment hnmg 32 by walls including eorkboard 43 and ground cork'43a.

Lmmg 33 is provided with an oblong shaped flange 45 which receives a conduit 46 which eartends through the walls 43 and 430 and pro ects slightly above the bottom wall 47 of coohng'compartment 30. Conduit 46 provldes a passage for air which is conducted y from the food compartment 32 to the cooling 4 compartment 30 and is-located at one side of cooling compartment 30. The top side wall 33a of lining 33 is also rovided with a cylin drica-l upwardly exten' ing flange 49 adapted to recelve the conduit 48 which extends through the wall 43and rojects above the 3 bottom lining wall 47 of compartment 30. It will be noted that the conduit 46 enters the .wall 47 and that the conduit 48 is located at the other end of compartment 30 and its cold 7 air entrance is substantially at the lowest por tion of said wall. Theair which passes from compartment 32 to compartment 30 is cooled in said compartment 30 and passes throughthe conduit 48 into the compartment 32. A

deflector 46a tends to cause the warm air entering the cooling chamber to be mamtained mo 90. i I chamber 30 at the highest point of the bottom 5 2 in the lowest and hence coolest part of the chamber.

The refrigeratingmechanism is the same as that shown in the reviously mentioned application and substantially the same as that shown in the patent to D. F. Kieth, 1,510,147, filed April 12, 1923. This mechanism comprises a generator-absorber and an evaporator-condenser 51. The generator-absorber 50 is located in the machine compartment 31 and the evaporator-condenser is ocated within the cooling compartment 30. Suitable connections between the generatorabsorber and evaporator-condenser extend through anopening 52' in the wall 37 and linin 36.

The front of the cabinet comprises two. main ortions 54 and 55. Portion 55 carries a horizontally disposed-angle iron 56 adja cent the top thereof. The angle iron is secured adjacent the center thereof to the front 55 by screw 57 (See Fig. 5). Angle plates 58 are securedto the lower ortion of front ppfition 55 adjacent the ottom thereof.

en assembling the cabinet the portion 55 is placed face down and the lining 33 of food compartment 32 is secured thereto. After the cork insulation is placed upon the lining 33, the back 23 is then laid upon the insulation. Tie-rods 59 are connected to the ends of the angle iron 56 and to the anchor plates 58 and extend throughout the width of the cabinet and through the back 23. The ends of the tie-rod are screw threaded to receive nuts 60 by which the back 23 is drawn toward the front. When the nuts are tightened the food compartment 32 and insulation therefor are clamped between the front 55 and back 23. When the food compartment 32 and insulation are clamped in position as described, the angle iron 56 may tend to bend, as shown in Fig. 5, but since the angle iron 56 is secured to the front adjacent'the center thereof, the iron is permitted to bend without distortingthe front.

The lower corners of both the front 55 and back 23 carrry lposts 61 and 62 to which gliders 63 are seen The upper ends of post 61 and 62 terminate below the bottom insulation for cabinet 32. A board 64extends throughout the width of the insulation and above post 61 in the front of the cabinet and board 65 is similarly located above the post 62 in the back of the cabinet. Wedges 66 are driven between the posts 61 and 62 and boards 64 and 65 to support the cork insulation and lining 33. In this manner slight variations in the dimensions of the cork lining and posts are readily taken care of.

The insulation on the back of the lining 33 s cut away and carries wood inserts 68 and the back 23 is secured to these inserts by Screws 69. The inserts are secured to the cork by a plastic material such as hydrolene and since the back 23 is secured thereto, the back of the lining 33 and insulation therefor cannot shift sidewise.

The cooling compartment 30, the lining 36 and the insulation therefor are built upon the insulation of top wall 33a of the lining 33. The sides 21 and 22 are then secured to the front and back of the cabinets. Then the top 24 is secured to sides 21 and 22. It will be noted that the back edge of the sides 21 and 22 do not engage the back wall 23 but can extend any distance beyond the back 23. Therefore, it is not necessary to provide sides of an accurate depth since said sides do not necessarily fit flush with the back 23. The top 24 and the sides 21 and 22 are made the same depth, therefore, the corners thereof meet in the back of the cabinet, and when the cabinet is placed against the wall, rear wall 23 cannot be seen, and, therefore, it is immaterial if said rear wall 23 does not fit flush with the back edges of sides 21 and 22 and top 24. I

The side wall 21 extends only along the side of food compartment 32 and ends adjacent the bottom of the machine supporting base 71 and the top 24 extends only over the cooling compartment 30. An L-shaped cover 72 encloses the side and top of machine compartment 31. Cover 72 is carried by side wall 21 and is provided at its lower end with a flange 73 which hooks over the top of side 21. The to of cover 72 extends over top wall 24 an is secured thereto by screws 74.

The front section 54 is removably secured to side wall 22 and front section 55 and can be removed without removing the portion 55 whereby access may be had to the front of the refrigerating mechanism within machine compartment 31. The front insulating wall of compartment 30 is rovided with an opening 77 which is closed by a plug 78 having a handle 79. When the front section 54 is removed, the lug 78 can be removed whereby the atten ant may view the interior of compartment 30.

Wall 37 between compartments 30 and 31 includes a removable portion 80 which when removed lays bare that part of the mechanism which extends through said wall. Therefore, when the top 24, L-shaped cover 72, and the top 40 of the compartment 30 are removed, the entire refri crating mechanism can be removed upwar 1y. I
